Krakatoa (Gunung Krakatau) is a volcanic island in the Sunda Strait between Java and Sumatra in Indonesia. It is part of Lampung province in Sumatra.


Travel Warning WARNING: Mount Krakatoa is an active volcano. The Centre of Volcanology and Geological Hazard Mitigation (ESDM), the Indonesian authority that watches over volcanic activities, shows the status of volcanoes above normal (Status Gunungapi Diatas Normal) on their website. Anak Krakatau erupted in Feb 2017. Access to Mount Krakatoa may be restricted.

The eruption of Mount Krakatoa in 1883 was one of the most violent volcanic events on record. A huge explosion (150 megatons of TNT) occurred as seawater hit hot magma and turned instantly to steam. The blast was heard over 4,000 km away in Australia and India. The Volcano Explosivity Index (VEI) of the eruption is 6 (colossal).

The whole volcano was destroyed because of the massive explosion. Parts of the volcano fell into the sea and caused giant tsunami (40 meters). The dust from the eruption reached the stratosphere and affected weather worldwide for several years. More than 35,000 people are killed by tsunami and eruption. Only about a third of the pre-1883 island survived the blast.

From 1927 to 1930, there were several underwater eruptions on the site of the old Krakatoa volcano. On August 11, 1930, a new volcano and island appeared. This new volcano and island are called 1 Anak Krakatau (Child of Krakatoa).


The island of Anak Krakatau, and the surrounding islands and seas, are part of the national park of Ujung Kulon.

Get in[edit]

You can reach Anak Krakatoa Island using boats from Anyer beach or Carita Beach in West Java, or Lampung in Sumatra.

From Java[edit]

The easiest way to get in to Krakatoa is by chartering a boat from the west coast of Java (province of Banten). Tour operators can be found in most of the coastal towns, such as Anyer or Carita. The range of the tour fee will be around Rp750,000-3,000,0000, depending on the number of participants and the number of days. The price will include transport, food, accommodation in a tent, and a guide.

From Sumatra[edit]

A cheaper but more time-consuming way to get to Krakatau is through the island of Sumatra (Lampung province). Lampung can be reached from Java via the frequent ferry service from the port of Merak. From the port of Bakauheni in Lampung, a yellow-coloured angkot (public minivan) can take you to Kalianda for about Rp12,000, and from there to the small harbour of Canti by another angkot (about Rp5,000) or by ojek (motorcycle taxi, Rp10,000). In Canti, you can make a deal with a fisherman, either for a day trip to Krakatau, or for a one-way trip to one of the accommodations. One full-day boat rental will cost you about Rp1,500,000. Around noon, there is a regular boat from Canti to 2 Sebesi island (one way Rp15,000). In Sebesi, you can also charter a fishing boat for a day, cheaper than in Canti.

Beware of strong current and large waves during August, September, October, and November.

Fees and permits[edit]

To enter the Kraktau area, tourists must obtain a permit from Balai Konservasi Sumber Daya Alam (BKSDA).
